Knowing the mineralogical limiting curve of the feed, a liberation
parameter Blib can be defined on the same mathematical basis
as the ratio of separation. The liberation parameter has to be the
ratio of the achieved liberation area and the 100%-liberation area
(A100L, Eq. (2)). The 100%-liberation area is enclosed by the perfect
separation and the perfect mixture. Henceforth, Blib will be stated
as the ratio of liberation
